1 This invention relates to a valve head construction, and more particularly, to a valve head particularly adapted to control the flow of liquid in a toilet, although quite possibly, the valve head has application to other devices as well.

The present application is a continuation in part of my previous application, covering a toilet, filed June 29, 1945, Serial Number 602,268, now Patent Number 2,443,214, issued June 15, 1948.

The application in question covers "a toilet construction wherein the toilet normally is enclosed within a wall communicating between adjacent rooms, and is adapted to swing on its mounting into either room.

The swinging toilet of the parent application operates, by its swinging into and out of the wall, a valve, and the present application relates to an improved construction for the valve.

The primary object of the present invention is to provide a valve head of far greater simplicity than that shown in the parent application, which will nevertheless discharge with full efiiciency all the functions required of the original valve head.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the glwlins, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings Figure l is a longitudinal section through the valve head, in which parts remain in elevation, mounted in a wall in association with a reservoir or tank, the position of the parts of the valve being shown as they appear when the toilet is swung out of the wall for use.

6 Claims. (01. 277-13) 'Referringto the drawings in detail, the refer en-ce numeral 28 is applied to an outlet pipe section. An inlet or feed 'pipe is designated 39, a reservoir or tank is 42, and a pipe 4| provides constant communication between tank 42 and the valve casing. These particular numerals referto correspondingparts in the parent case, and by reference to Figure 3 of the parent case, the location of the valve of the present invention, and the structure whose place it takes, can be immediately noted. 7 r

In the present invention a valve casing Shas' a main or outlet valve-chamber 6 and a secondary or inlet valve chamber 1. These are in communication. The inlet feed pipe 39 opens into inlet valve chamber 1. The outlet valve chamber not only communicates at one end with the inlet chamber 1, but at its top opensinto pipe 4| leading' to the reservoir 42, while at itsbottom it' opens into the outlet pipe section 28. v I

The valve casing 5 and the outlet pip'e' section 28 are relatively rotatable members. As ap-'' plied to a swinging toilet of the type described in the parent application it is the outlet pipesection 28 which has rotatable movement, while the valve -casing5 is mounted stationarily." I' can conceive of other applications, quite pos-' sibly' not used in conjunction-with aswinging toilet, wherein the valve casing might be th'e rotatable membergwith the 'pipesection sta tionary, or whereinboth members are mounted for rotatable movement. In anyevnt, the same valve operation would result, as will beapparent from the description'to be provided hereinafter? For the purpose of providing a leak-tightcon nection between the casing and pipe section, while yet permitting relative rotation','the pipefsectiojn is provided at its upper end with an outwardly di rected casing is provided with an inwardly directed fiangeor shoulder 9. Packing 'l'llisinterposed between the flanges, and thus'the parts'are permitted relative rotation while yet providing a leak-tight connection. l

' Extending into the outlet valve chamber 6, from the end of the pipe section 28,"are diametrically opposed pins ll. As applied to a swinging toilet,

not shown, to which outlet pipe section 28 is fixed ly connected, pins l l are in line with a line drawn longitudinally through the center of the hopper.

If valve casing 5 extends longitudinally of the wall in which the hopper is normally enclosed, it becomes apparent, by noting the position of pins 1 I in Figure 3,.that this is their position whenthe hopper is swung out of the wall in either direcannular flange or shoulderftjwhile the tion, and is disposed at right angles to the wall, for use. Figure shows pins II in their position when the hopper is enclosed within the wall and is not in use.

Also carried by the top of the outlet pipe section 28, and extending into the chamber 6, are diametrically opposed lugs I2, which are equidistant from the pins II, and which preferably are smaller than the pins.

Extending across the-open end of the pipe section, between pins II, is a cross member I3, the purpose of which will be apparent.

The invention embodies the main or outlet valve, compositely formed of co-acting semi -circular valve blocks I 4 and I5. These are so proportioned that when they are brought together into engagement, as in Figures 1 and:3,.they-close ofi the valve chamber 6 from the outlet pipe section 28. When spread apart, however, as in Figure 4 and Figure 5, the valve blocks permit communioati'on between the chamber and pipe section.

Rotatable movement of the pipe section 2:Brelativeto the valve casing is. adapted to spread the valve blocks apart, or draw them together, as the case may be. When the hopper,v not shown, is s-Wungi full-y out of its enclosure, in either direction, the. valve blocks are brought intov engagement with each other (Figure 3) so as to close communication between the outlet valve chamber and the pipe section. When the hopper is positioned fully within its enclosure, the valve blocks will have been spread apart (Figures 4 and 5).

This is accomplished as follows. The under side of valve block I4. is formed with a groove I-6 adapted to receive either pin II. This groove is of generally curved appearance, lying close to the straight or inner side of the valve block. and: for the greatest length of said inner side, as clearlyseen from Figures 3' and 5. The groove opens at both ends, and has: an intermediate portion curved close; to the straight side of the block with the end portions being disposed somewhat further away trom said side.

Block I5. has a similar groove I1 formed in. its under side, and when the valve blocks are in engagement with each other, the. ends of both grooves communicate: In this position of the valve. blocks, the pins I I are positioned directly in the line of engagement of the blocks so as to be disposed partlyin both grooves;v

In the under side of blocks Hi and t5, there arealso formed semi-circular outer grooves l3 and I9 respectively. These are disposed close to the outer, curved sides of the respective blocks.- These grooves receive lugs. I2. When blocks MI and are in engagement with each other,v the grooves I8 and I9- also communicate at their ends, as seen from Figure 3.

When the blocks are spread apart as in Figure 5, rotation of the pipe. section 8 through. 90 draws-the blocks together. By' extending the ends of the grooves I6 and 11 away frornthe direction of rotatable movement, the blocks are brought together more rapidly than would be the case if the grooves were straight.

During this movement of the pipe section, the lugs I2 will enter the outer grooves I8 and I9. As pins I I move into the ends of the inner grooves, pins II will no longer act to bring the blocks togethei'. However, lugs I2 complete the task, and when the lugs I2 are in the position shown in Figure 3, they will have fully locked the blocks together. Cross member I3 of the pipe section will be positioned directly below the line ofengage- '4 ment, and assist in providing a proper seal against leakage.

One end of the valve casing 5 is bored to permit slidable reciprocation of a guide rod 20 mounted therein. One end of the guide rod is threaded for engagement in a threaded bore 2| of valve block I4.

A valve rod 22 is extended through the opening communicating between the outlet and inlet valve chambers. but does not. close off the opening against the passage of liquid. The valve rod 22 is also threaded at one end for engagement in the bore 2| of block I4. Block I5 has a smooth bore to: permit the valve rod to be slidably reciprooated therethrough. V

The end of the valve rod 22 that projects into the. inlet. chamber I is provided with an inlet valve 23' which can be detachable if desired, as shown in Figure 5. Inlet valve 23 has longitudinal relief passages 2d. The purpose of these is; to permit, the escape oi liq id which m h otherwise-be trapped" in the inlet chamber t duringreciprocation oi the inlet valve.

The valve head: is readily assembled; asfollows. Outlet. pipe sec-tion 28;, equipped withpins I I and lugs $23,15- drapped down through thelarge opening at the top of the valve casing 5 until its end is flush. with the floor-oi the; outlet valve chamber I3. Prior to: lowering the pipe section 2.8 in th manner described, the, pair of valve blocks is loosely positioned: on; the pins H and lugs i2. This is. done with the pins and lugs in the position Shown in Figure 3.

With the blocks seated on its upper end in this manner; the pipe section is now lowered as stated. Guide rod 20 is now' extended through the bore of the valve casingand is threaded into block I t, the outer end of the guide rod being iio-rrn-ed: with a kerf 2-5: adapted to receive a screw driver bit. I

The inlet valve rod 22, equipped with its inlet valve 2:3,; is: now extended through the bore: of biock' I 5, and is'threaded into. bore ZI of block id. The outer end of the inlet valve 23 is formed with a. kerf- 2E'rfor this: purpose.

The operation of the device is as follows. The assembled valve head, connected to pipe iI and inletfeed pipe 3%, and joined through suitable unions to pipe members extending from opposite sides of the enclosure wall, will have its parts in the positions shown in Figures 1, 2 and 3, when the hopper is swung outwardly from its enclosureand is in use. At this time, the main or outlet valve is seated over the outlet pipe section, but the inlet valve 23 is permitting water to enter the inlet valve chamber 1 through the feed pipe 3.9. The water so entering is forced into the main valve chamber 6 and fills reservoir 42.

' When the hopp r is swung back into the enclosure, it partially rotates the pipe section 28, and this opens the main valve as shown in Figures 4- and 5, at the same time moving the inlet valve 23 into a-position closing feed pipe 39. As a result, the reservoir 42 is emptied, and the water stored in the tank is released to flow by gravity through the outlet valve chamber 3 and downwardly through pipe section 28 into the hopperat any suitable point. It flows outwardly from the hopper into a soil pipe, not shown.

It may be noted that the operation is. the same whetherthe hopper is swung from its enclosure in one direction, or in the opposite direction.

What is claimed is:

1. A valve head comprising a casing formed with a chamber having spaced openings, spreadable valve blocks in the chamber and adapted to close flow through one opening when brought against each other, and to permit flow through said opening when spread apart, means responsive to movement of one of the blocks adapted to close the other opening when the blocks are spread, and to close said last-named opening when the blocks are brought together, and means for spreading the blocks and bringing them toether.

2. A valve head as in claim 1, and wherein the means last named comprises a pipe section connected to the casing for relative rotatable movement and communicating with the chamber through the first-named opening, said pipe section having projections engaging the blocks and adapted to spread them apart and bring them together, on rotatable movement of the pipe section relative to the casing.

3. A valve head as in claim 1, and wherein the last-named means comprises a pipe section connected to the casing for rotatable movement relative to the casing, the pipe section including pro- J'ections extending into the chamber, there being grooves formed in one face of each block adapted to receive said projections.
